9' Claims. 1 This invention relates to forms for supporting shoes and more particularly while their uppers are being shaped and smoothed, and has for an object to provide a form arranged to support shoes of different sizes and presenting a smooth surface to the inside of the shoe and against which the shoe upper may be pressed.

For a complete understanding of this invention, reference may be had to the accompanying drawings in which Figures 1 and 2 are side and top plan views, respectively, of a form for supporting a shoe, the position of a shoe supported thereon being shown in broken lines in Figure 1.

Figure 3 is a detail sectional view on line 3-3 of Figure 1.

Referring first to Figures 1, 2 and 3, a shoe supporting form I is shown comprising a central section 2 of the general shape of the rear portion of a last and including the upper portion of the last against which the top edge of the shoe upper may engage. This section 2 terminates short of the sole face of the form which is composed of a pair of sections 3 and 4. Each of the sections 3 and 4 is pivoted to the section 2 adjacent to its rear end as on the pivot screws 5, so that by separating the forward ends of the sections 3 and 4, the sides of the form may be expanded and by pushing them toward each other they may be con- };rfacted. Forms I may be made in rights and e ts.

In order to present a smooth surface to the in side of a shoe placed on the form and for other purposes, as will later appear, a sheet material cover I encloses the sections '2, 3 and 4. This sheet cover, which is preferably but not necessarily copper or other metal of good heat conductivity, has its top edges inwardly turned as atl2 to overlie the sole faces of the pair of sections 3 and 4 and to-these faces these overlying portions are secured toward the rear ends of the sections 3 and 4 as by screws l5. Opposite edges of the cover I0 which overlie the side faces of the section I have attached thereto electric heating elements 20, these elements being attached to the inner face portions of the sheet metal cover ID on the inside and being received in recesses 2| in the section I adjacent to its edge. The sheet metal casing I0 is also secured centrally adjacent to its rear end to the exposed face of the section 2 as by a screw 23. The central section 2 is also provided with a jack pin hole 25 so that the form may be mounted sole-side up on any suitable form or jack to present a shoe placed thereover with its sole face uppermost.

The forward portions of the sections 3 and 4 may be forced apart, thus to expand the form, the casing in being free to conform generally thereto, and more particularly when the upper of a shoe supported on the form is pressed thereagainst, being unattached thereto forwardly of the screws 15 and 23, and for this purpose the confronting faces of the sections 3 and 4 are recessed as at 26, the rear face of the recess being beveled rearwardly as shown at 21 in Figure 1. Against this beveled face and between the sections 3 and 4 may be positioned a conical point 23 of an expanding screw 29 which extends upwardly and rearwardly through a threaded hole 30 in the section 2. This screw 29 may be provided with a threaded socket 3| in its outer end for the reception of a threaded element 32 of a handle 33. This handle 33 is preferably made of some heat insulating composition, such as one of the synthetic resins, so that it may be turned by the fingers of the operator as desired without becoming uncomfortably hot from the effect of the electric heaters 20. By turning the screw 29 inwardly so that its point 28 is pressed against the adjacent edges of the Walls 21, the sections 3 and 4 may be forced apart at their forward ends. By relaxing this screw, these forward ends are pulled together as by a coil spring 35 engaged at opposite ends with pins 36 as secured in the sections 3 and 4 and projecting into recesses 31 therein within which the spring ends are engaged therewith.

The sheet metal covering [0 provides a smooth exterior surface for engagement with the inside of the shoe upper placed over the form and bridges across the junctures between the elements 2, 3 and 4, regardless of the widthwise adjustment of the sections 3 and 4. As shown, also,

this metal cover extends substantially throughout the shank portion of the form so as to engage throughout substantially the entire heel end and shank portion of a shoe placed thereover. By reason of the heating of this metal cover, the entire inner face of the shoe throughout the heel end and preferably also substantially throughout the shank portion, is subjected to heat which thus shrinks the lining and as the shoe upper is pressed thereagainst, as will later appear, irons out any wrinkles which may be present therein when the shoe upper is treated. The expansion and contraction widthwise of the form makes it possible to treat shoes of considerable variation in size and width on the one form.

This supporting form as shown is particularly well suited for supporting shoes in connection with mechanism for pressing the shoe uppers shown in my application Serial No. 600,924 filed June 22, 1945, as a division of this application, for Shoe upper shaping and smoothing machines which has matured into Patent No. 2,433,266, granted December 23, 1947, before as a division.

From the foregoing description of an embodiment of this invention, it will be understood by those skilled in the art that various changes and modifications might be made without departing from the spirit or scope of this invention.
